Hello, I have a C# file that contains 591 5-digit hexadecimal numbers in the format '0x?????', and I wish to replace them with their number plus a set hexadecimal number. How can I do that, even if I have to download new software? I really do not wish to type out the exact values by hand, as that would take days. Thanks in advance.

What I have tried:

I have tried figuring it out using the Notepad++ Python Script plugin, but it appears that it does not support exactly what I want to do, judging from the documentation alone.

I don't know of any tools that will do this, the problem being the addition of a number to another in the replacement value.

You will probably have to write your own tool to do this. This is mostly going to be reading a text file and string manipulation so it shouldn't be too difficult to do.

Isn't this ok?
long res= Convert.ToInt64("0Xfffff", 16);

Okay, I am seriously facepalming right now. Easiest solution ever. Just add the value directly to every single result in Notepad++:

Find: (0x[0-9A-F]{5});

Replace: \1 + 0x617A0;

I have no idea why I was trying to edit the numbers themselves when I could simply add to them directly in the source file... Yeah, epic facepalm moment.

Erm ... that doesn't do what you originally asked for: it adds two text strings.
So if the file contained:

0x00000;
0x10000;
0x11000;

The resulting file contains this:

0x00000 + 0x617A0;
0x10000 + 0x617A0;
0x11000 + 0x617A0;

From your original description I expected you wanted this:

0x617A0;
0x717A0;
0x727A0;

Either you need to be a lot more specific when you ask a question, or your solution doesn't work.

I never said that the file contained ONLY those hex values, and I also said that it is a C# file; in other words, code. This fact alone makes the fact that it isn't only hex values self-explanatory. Here is just one line of the code with function names changed for privacy:

br.position = 0x3422C;

This line is using the BinaryReader function (called as br) to seek to 0x3422C. The project is for a binary file editor for a specific file. All lines that have hexadecimal numbers are lines that define offsets within the binary file.
